Research on Properties and Application Technology of CMOS Image Sensor with Rolling Shutter
In order to research the specific applications of CMOS image sensor rolling shutter
this paper research with specific CMOS image sensor. First
this paper introduces the principle and characteristics of global shutter and rolling shutter of the CMOS imager
it analyzes the impact of rolling shutter on measurement precision of the imaging system based on CMOS imager .Imaging experiment is taken to test the analyses of the rolling shutter. Then
an original method for computing instantaneous 3D pose and velocity of fast moving objects using a single view is presented. It exploits image deformations induced by rolling shutter in CMOS image sensors. Finally
a general perspective projection model of a moving 3D point is presented. A solution for the pose and velocity recovery problem is then described. Results indicate that some aberrations appears in faith
and the aberration degree has close relations with some parameters of CMOS imager like integration. After experiments can minimize error in the case of moving objects by the pose and speed parameters
the calculation error is under 2.5 percent. Experimental results with real data confirm the relevance of the approach. The resulting algorithm enables to transform a CMOS low cost and low power camera into an original velocity sensor.
